What can impact the epidermis as one ages?

As individuals age, a notable physiological change that occurs is a decrease in oil production in the skin. Sebaceous glands, responsible for producing natural oils (sebum), become less active over time. This reduction in oil not only leads to drier skin but can also impact the skin's barrier function, making it more susceptible to irritants and allergens. Additionally, decreased oil production may result in an increased appearance of fine lines and wrinkles, further highlighting the importance of maintaining skin hydration and using moisturizers as one ages.

In contrast, increased elasticity, increased thickness, and improved moisture retention are generally not characteristics associated with the aging epidermis. Instead, the aging process typically involves a loss of elasticity, a thinning of the skin layers, and challenges in retaining moisture, making the recognition of decreased oil production significant in understanding skin changes with age.
